ABSTRACT:
A mixture control device for a fuel-injected internal combustion engine in which an air flow meter in the induction tube is associated with a slide valve which opens and closes a fuel metering orifice. A differential pressure valve is connected across the metering orifice and one chamber of the differential pressure valve is connected to a servo-motor which moves the main fuel control rod of the fuel injection system. When the amount of fuel delivered to the engine is different from that metered out by the orifice, the pressure in the differential valve changes, causing a temporary admission of pressurized fuel to the servo-motor, which adjusts the position of the main fuel control rod until equilibrium is re-established. Several embodiments are presented, including exhaust gas recycling.
